What Are the Reasons Why the Tire Pressure Warning Fault Cannot Be Cleared?

The reason why the tire pressure warning fault in a car cannot be cleared is that the tire pressure in one or several tires is too high or too low. In this case, it is necessary to add or release some air pressure, and then perform a tire pressure reset to restore normal operation. The method to eliminate the car tire pressure alarm is as follows: After handling the tire pressure fault, first turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data, and finally, the fault light on the dashboard will turn off, indicating the completion of the tire pressure reset. Tire pressure monitoring is the real-time automatic monitoring of tire pressure during car driving, and it alerts the driver in case of tire leakage or low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data is displayed. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire alarm systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the above two systems. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the defect of indirect systems being unable to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data of the actual pressure in all four tires like a direct system.
